Polyvinyl chloride is used in furniture and clothing and has recently become famous for the construction for doors and windows. It is done to find out any harmful effect the polymer might have to the environment. It is measured as units of carbon dioxide. Whereas the MFR (Figure 3) is a very common measurement, it is not a pure measurement of viscosity, however. Thermosetting materials start as liquids/syrups, often called "resins", as powders or partially cured products ("preforms") which need heat for the shaping phase. To do this, researchers are working to develop polymers that, when compared with their non-sustainable counterparts: use renewable feedstocks, such … The double bonds in monomers break and they join to form a big molecule. Natural polymers were used for their chemical properties long before they were understood in the chemistry laboratory: Wool, leather, and flax were processed into fibers to make clothing; animal bone was boiled down to make glues. The use of polymers as scale inhibitors and dispersants in industrial applications is well known to the water technologists. An estimated 86% of all plastic packaging is used only once before it is discarded, producing a stream of waste that persists in waterways and landfill, releases pollutants and harms wildlife.
